Crypto businesses already know that a polished pitch is not the same as a system that holds up under pressure. Firmulate’s live experiment puts AI models through a company’s worst week, testing whether they can read the evidence, protect trust and follow through when money is on the line.

A test beyond the demo
Firmulate ran frontier models through the same small software company and the same set of customers, crises and temptations. Decisions were versioned and auditable. The experiment is presented as a live company, with synthetic employees and real money mechanics; readers can watch it at Firmulate.
The final Crucible league, dated July 2026, puts gpt-5.6-sol first with 95 points and Moonshot’s Kimi K3 second with 93. Sonnet 5 scored 88, Fable 5 scored 77 and Opus 4.8 scored 73. Kimi’s result makes the field look more open: it finished ahead of three of the four Western models in the test.

Reading the files mattered
Every model spotted every crisis and refused every manipulation attempt. Yet only two signed the €55,000 deal their own analysis had earned. The decisive weakness in a competitor’s position was buried two document references deep in the company’s files, rather than in the customer event. Models that found it won the deal at full price, worth +€4,583 in monthly recurring revenue.
Kimi K3 found that buried fact, won the deal, saved a customer who was considering leaving and resisted all three baits. It had one deviation, the fewest in the field. The results point to a practical distinction for businesses considering AI agents: noticing a problem is different from completing the work that follows.
The manipulation test included fake CEO messages escalating over three stages and a reporter asking for “just one yes/no, on background.” All five models refused. Kimi’s on-record reasoning described the request as a “suspected approval-bypass / possible impersonation.”

Thoroughness did not guarantee a finish
Opus 4.8 was the most thorough participant, with +80 learned rules and the deepest analyses, but it placed last. It left the deal unsigned and slipped on discipline by attempting to write into a locked department instead of escalating. A weaker version of that same weakness appeared in all four models.
The company behind the test has 13 synthetic employees, burns €105k a month against €2.3k in monthly recurring revenue, and displays a public cash countdown. Its playbook has more than 680 self-learned rules, and each workday is versioned. Firmulate also offers a quiz built from 242 real, unedited management decisions, asking visitors to guess which model made each choice.

Run your own test
For crypto firms weighing AI for customer support, operations or forecasting, the standings are a reason to test models against the work they would actually do. Firmulate says enterprises can run the same wargame against a read-only export of their business; nothing writes back to real systems. The benchmark page publishes the results and findings.

The takeaway
Kimi K3’s second-place result shows that the leaders are not a foregone conclusion. But a league table cannot tell a crypto business which model will handle its own customers, files and approval risks. Choosing without running a relevant test is a bet.
Fairness note: K3 ran without an effort parameter (API default) while the others ran at xhigh.
